>>>>having been away from the car business 13 years this year(YEA!!!) i think i remember, but not sure being advised that if i am hung up on synthetic oils to not run them or combos (pennzoil seminar )at the time, in new engines until broken in or anot 1000 miles or more. some rings might not seat if they see such slippery oils during breakin? now fer the flames...

No flames, Tim, but we ran this subject into the ground a couple of weeks ago.  I learned a lot about ring-seating, honing, and oils from some very well-informed people on this list.

I think the consensus on rebuilt engines was, it's a good precaution to run regular oil for the first 1K or so, changing once or twice before 5K, then OK to go synthetic after that.

As far as "new" engine precautions go, there don't seem to be any with regard to synthetic oil.  Some OEMs put synth in there at the factory.
